Mycelium-based Biochar Supported Sustainable High-Performance Phase Change Materials: Systematical Development and Practical Applications

Phase change materials (PCMs) present a promising solution to address the challenges of intermittent and fluctuating solar thermal energy. However, the widespread use of organic solid-liquid PCMs is hindered by leakage, low thermal conductivity, ineffective solar thermal storage, and flammability. This project aims to overcome these limitations by utilizing the unique growth properties of mycelium, combined with 3D printing technology, to develop high-performance PCMs that present a promising solution to address the challenges of intermittent and fluctuating solar thermal energy. The main objectives include: (1) to develop and optimize 3D-printed mycelium aerogels for effective PCM encapsulation; (2) to improve the thermal conductivity and flame retardancy of the PCM composites through carbonization; (3) to achieve a sustainable and scalable PCM manufacturing process; and (4) to demonstrate the high performance of these PCM systems in practical applications such as solar energy capture and thermal management. This approach offers a sustainable and scalable solution for PCM systems, ensuring high thermal stability, long-term durability, and reduced energy consumption in the manufacturing process. The project has the potential to transform PCM-based thermal storage systems for solar energy harvesting, temperature regulation, and energy efficiency in buildings and industrial applications, providing an innovative, interdisciplinary framework for the development of versatile and sustainable PCMs.
